SMALL PARTICLE SIZE HYDRATED ALUMINA AS AN IMPACT SYNERGIST FOR IMPACT MODIFIED VINYL HALIDE POLYMERS |
| 摘要 |
Very finely divided hydrated alumina with a particle size of less than about 1 micron is useful as a filler material for polymeric vinyl halide materials and acts synergistically with conventional impact modifiers to improve Izod impact strength. The ratio of hydrated alumina to impact modifier is usually from about 1:2 to about 8:1. |
